That is Mac centric. At the time, the bus on the Mac was too slow to support the Toaster or really anything like it. So the solution for the obsessive-compulsive Mac freak of the day that would look like a acid trip in a shower with a mirror and brillo pad if they touched anything but a Mac was to make a GUI front end for the Mac and connect it to an A2000/Toaster with a serial cable.
Everyone of my vintage remember the Todd Rundgren bit where he had to have a Mac shirt on when photographed near and Amiga when Amigaworld did the article on his Toaster-generated video?
